However, Daniel bounced back as he won the third set comfortably to clinch the match.
Sela also took the second set by the same score to seal a 6-4 6-4 victory in 91 minutes against world number 24 Edmund, who replaced the injured Andy Murray as British number one earlier this month.
Federer and Delbonis will return to centre court on Sunday, tournament organisers confirmed. "Now we're in Indian Wells and that's my focus and not what I have achieved in the past". "Nerves were there. I made so many unforced errors". That's almost double the winners he had.
"He is undoubtedly one of the greatest players ever so it was a great privilege", said the Zimbabwean, who idolises the Serbian star. "So naturally, it's all a change". "When you go from night to day, (normally you are) playing a different opponent, so naturally, it's all a change". It was actually quite interesting. The surface doesn't react so much; the ball doesn't travel so fast.
Krajinovic had no answer for Federer's serve or relentless return game and ended up winning just 31 of the match's 93 points.
Roger Federer will play Jeremy Chardy in the last 16 at Indian Wells after beating Filip Krajinovic. Whatever Federer is doing in the offseason, it's working. He lost to Chung Hyeon in the Australian Open fourth round in January before undergoing the surgery.
Keep in mind that during his stellar start in 2017, Federer looked beatable at times. At the Masters 1000's, when the format was different, it was best-of-five (sets) in the finals.
It goes without saying Federer's perseverance has been as key to his success as any ace or victor.
Federer and 10th seed Djokovic both came into the tournament seeking to become the first six-time victor of the event.
So, is there added pressure this time around?
"I was playing aggressive and feeling like he was not loving my slice, and then also mixing in with drop shots eventually", Federer said, as quoted on ATP's official site.
The ex-world No. 1 says he is yet to find his rhythm in practice as well but is glad he recovered sooner than expected from his surgery and that he managed to get on a match court this week.
